In May, a confidential informant provided the name of a potential suspect: Bobby D. Dutton, 19, of Mountain Home.

Detectives interviewed Dutton’s family, friends, and associates.

Witnesses told investigators that Dutton drove to a mobile home park in Midway immediately following the collision.

The witnesses, according to Montgomery, said Dutton appeared “very upset and frantic.” He reportedly told the witnesses, “I hit someone.”

Dutton then indicated he needed a change of clothing and asked the people present to help him burn the clothes he wore.

Upon hearing the witnesses statements, deputies asked Dutton to come to the sheriff’s office in May for an interview. He refused.

Detectives interviewed him on June 10, but he disclosed nothing, Montgomery said. During a subsequent interview on July 20, Dutton asked for an attorney and made no statements.

On Sept. 21, Investigator Scott Thrasher prepared an affidavit for an arrest warrant. The prosecuting attorney filed the charge, and a Baxter County Circuit Court judge issued an arrest warrant on Sept. 27.

When detectives went to arrest Dutton, they learned he had overdosed on drugs in Marion County and was being treated at the Baxter Regional Medical Center. Dutton died five days later on Sept. 30.

Montgomery said the county coroner's office could not determine if the overdose was accidental or intentional.

Investigators never served the outstanding warrant on him.

Following his death, Dutton’s family told investigators he had confessed to running over Foreman on the evening in question, Montgomery said.

The sheriff’s department has closed the case.

Montgomery thanked the public for their assistance in providing tips, leads, and other information during the course of the year-long investigation.

He also offered his appreciation to the following for their help and support:

In the past few months, a number of high-profile men have been accused of sexual harassment and sexual assault. Allegations have led to resignations in Congress - and may have made a difference in a key Senate race.
